    1986 gimbal housing, gimbal ring, bellhousing, outdrive swap on to a 1968

    As Bondo said you will need to use everything from the engine back. I think the 470 flywheel housing will bolt to the 160. The SEI drive should work out ratio wise. If the SEI has the longer driveshaft it should connect to the engine. The front mount will be further forward Some early 160...

    That skin stuff you saw is common in older fuel systems. Sometimes it looks like very fine hair. The screen in the suction tube has to come out. The crazy part is if the gas in the filter tube is dried out you will be able to blow through it with your mouth, but with gas it will cause a...

    It will not be compatable with a V6 or V8 application. It will work with a 2.5 and a 3.0 as well as the style engine you have. The main difference is the centering boss that protrudes where the driveshaft comes through and centers in the inner plate.
